Rep. Kyrsten Sinema, D-Ariz., who is running in a tightly contested U.S. Senate race, implied that her home state produced "crazy" in a 2011 speech in which she also promised to advise liberal activists on how to "stop your state from becoming Arizona."

"Calling Arizonans crazy and having particular disdain for Republicans when she wants Republicans to vote for her is unbelievable," McSally told reporters at a roundtable with business leaders and Gov.

"She was frustrated that no one in the state legislature was standing up to out-of-state special interests working to take away health care from children, make tuition more expensive, and take job security away from working families," Sinema spokeswoman Helen Hare said in a statement Thursday.

"People are saying the tea party, the tea party.

Sinema led McSally by nine points among women, 14 points among voters under age 45 and by 29 points among Hispanic voters.
